Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 327 Issued at 2200Z on 23 Nov 2017

IA.  Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (24 Nov, 25 Nov, 26 Nov).

IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 504 km/s at 22/2203Z. Total IMF reached 6
nT at 23/2030Z. The maximum southward component of Bz reached -4 nT at
23/1817Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 4658 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (24 Nov) and quiet levels
on days two and three (25 Nov, 26 Nov).
